Which pitfalls lurk in the networking of our world? How does data get from the sender to the receiver across different technologies and layers? At KOM, students learn the fundamentals and new research on communication networks and systems.

Overview

In the lecture Communication Networks I, the basic technologies of today's communication networks are presented and analyzed, especially with regard to today's most important communication infrastructure: the Internet. We look at the basics of digital circuit technology in the lecture Logic Design.

Many other lectures then build on the basics from the Communication Networks I module. The module Routing, Switching and Forwarding looks at data forwarding and routing, and thus at issues that hold the Internet and other communication networks together at their core.

In the module Application Protocols on the Internet, we take a close look at how typical Internet applications - from the World Wide Web to file distribution applications like BitTorrent to cryptocurrencies - work under the hood and how to approach it if you want to successfully implement such applications yourself. The module Transport Protocols and Their Design takes an engineering perspective and analyzes the protocols that make many parallel data flows and their coexistence on the Internet possible in the first place - first and foremost TCP in its many variants.

The lecture Communication Networks II by Prof. Steinmetz deepens the insights into the Internet architecture in its overall picture including its most important applications like mail, World Wide Web or file transfer.

Communication Networks II will be offered for the last time in winter term 2023/2024.

In addition to the lectures, KOM offers exercises, seminars, project seminars and practical courses. In these, current development topics from the field of multimedia communication systems are considered. The topics are determined by the specific research and work areas of the staff members and convey technical and first scientific competences.
